ADJUSTABLE EXTt-ZRNAL JOINT FOR ESCAPE-PIPES.

SPECIFICATION forming part of Letters Patent No. 559,305, dated April28, 1896.

f u u an January 23,1896. Serial No. 576,502. (No model.)

To all whom it may concern;

Be it known that I, FREDERICK R. NIES, of Swampscott, county of EssexandState of Massachusetts, have invented an Improvement in AdjustableExternal Joints for Escape-Pipes, 850., of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters and figures on the drawings representinglike parts.

This invention has for its object the production of an adjustableexternal joint for escape-pipes, whereby the same is convenientlyadapted for use on roofs of different pitch.

Figure 1, in vertical section, represents a portion of a roof with myinvention applied thereto, the dotted lines illustrating the adjustablefeature of the invention. similar sectional view showing a modified formof paeking-retainin g member or sleeve. Fig. 3 is a like view of anotherform of the supporting-hub. Fig.4 is a sectional view of yet anothermodification of the supporting-hub, and Fig. is a sectional view showinga modified form of sleeve.

In carrying out my invention I prefer to make the supporting-hub a andits base or flange a of lead, copper, or other suitable metal, the hub abeing herein shown as having its rear wall a curved from base to top andhigher than its front wall a the base being at an angle with relation tothe hub, so that the hub is obliquely truncated, as it were, for apurpose to be described. The base or flange a is overlapped by theslates or shingles at the upper side, and at the lower side may lap overthe upper ends of the first tier of slates or shingles in usual mannerto prevent entrance of moisture thereat.

A sleeve or collar (shown in Fig. 1 as two.- part) is adapted tosurround the escape-pipe P, (see dotted lines, Fig. 1,) the upper part bof the sleeve, preferably of cast-iron or other rigid metal, havingpreferably an internal shoulder b to sustain the packing p, molten leadbeing thereafter poured into the space above the packing between thepipe P and the sleeve in well-known. manner, as at 12,

Fig. 2 is a and as the opening of the joint is horizontal the lead canbe poured directly. The hardened lead thus makes a solid water-tightjoint entirely around the escape-pipe and between it and thestrengthening part b of the sleeve. The portion Z) of the sleeve may bemade of copper, lead, or other similar metal, having its lower endbeveled at I)? and resting on the hub o, and preferably pivotallysecured to the front wall a thereof by a suitable rivet 10, so that thesleeve may be adjusted on and relative to the hub according to the pitchof the roof, the curvature of the wall a of the hub being strucksubstantially with as its center.

In Fig. 1 a roof R having one pitch is shown in full lines, and it willbe seen that the back part of the sleeve rests on the curved rear wall aof the hub very near its top, the packing and lead joint tending toretain the hub and sleeve relatively fixed. If desired, the part b maybe bent or squeezed in more tightly about the hub for greater protectionagainst entrance of moisture. The dotted lines in said figure show aroof R of much steeper pitch, so that the rear wall of the hub israised, and supposing the pipe P to remain in the same position the topof the hub would be cut off in about the line 20, so that the two parts,hub and sleeve, would 00- operate with each other on the steeper pitchedroof just as they did on the roof shown in full lines. For a stillsteeper roof the hub would be trimmed off still more at the top, whilefor one having an intermediate or a less steep pitch the amount takenfrom the top of the hub would be less.

Should it be desirable to make the sleeve in one pieceas, for instance,of cast-ironit would be preferably made as shown in Fig. 2, the sleeve 0having preferably a packingsustaining shoulder or support 0, and an internal annular groove 0 near its beveled bottom end, into which a gasketo of rubber or other suitable material could be inserted to maintain thejunction between the sleeve and the hub a water-tight, as the sleevecould not be altered in size if made of cast-iron.

The adjustable feature of the device is not changed in the least by thislatter construction, the sleeve 0 being preferablyconnected to the hubaby a rivet 10.

In Fig. 3 I have shown a convenient form of hub when made of cast-iron,as is very desirable at times, the hub d in such case having formedtherein a series of grooves or thin portions 1 2 3 4 around its upperend, converging toward the front wall, so that by chipping a portion maybe removed from the top of the hub according to the pitch of the roof.Vhen the hub and sleeve or lower portion of the latter are made of asoft metal, no packin g or gasket is usually required between them atthe lower end of the sleeve; but if the sleeve be made of rigid hardmetal such a packing maybe found desirable, or when both sleeve and hubare of non-malleable metal.

Instead of cutting off the top of the hub, as hereinbefore described,Imay make it, as shown in Fig; 4, in several sections, thelowermost onefhaving a flange or laterally-extended base f to rest upon the roof.Other sections f and f are adapted to fit over the main portion f, saidsections having inclined tops and pivotally connected to the portion fby a suitable rivet 60.

1f the roof is very flat, the parts would be pulled out more or lessinto the position shown in Fig. 4, and the more the roof was inclinedthe farther down the parts would be telescoped, it being obvious thatthe slope of the top of the hub may be varied by the means described.

In Fig. 5 I have shown means for making a tight, moisture-proof jointbetween the escape-pipe P and the surrounding sleeve member 0 The saidmember is made of lead or other suitable compressible metal, and afterit is placed over the pipe P and in proper position its upper end iscontracted, as at 0 to fit tightly about the pipe, and a clamping-ringis forced over or drawn up tightly about the contracted portion 0 of thesleeve, to maintain the joint tight and moisture-proof. The base of thesleeve 0 may be mounted on the hub in the manner hereinbefore described.

My invention is not restricted to the pre cise construction herein shownnor to any particular metal or metals.

From the foregoing it will be obvious that the adjustment of theroof-joint to roofs of different pitch is an easy matter, requiring buta short time, the adj ustability obviating the manufacture of a seriesof hubs having their bases or flanges at different angles thereto tocorrespond to different roof-pitches.

The pivot connection or rivet 10 is not essential, but it is a greatconvenience in shipping the joints and also in setting them up. Afterthe packing and poured joint the sleeve will usually be held in place bythe escapepipe without other aid.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is-

1. An adjustable external oint for escapepipes, &c., consisting of anobliquely-truly cated upturned hub having a laterally-extended base torest upon the roof, and a sleeve adapted to support a packing between itand the pipe above the roof, said sleeve being telescopically connectedat its lower end to the hub,whereby the joint may be adj usted to thepitch of the roof, substantially as described.

2. An adjustable external joint for escape pipes, &c., consisting of anupturned hub having an inclined upper end and provided with alaterally-extended base to rest upon the roof, and a rigid metallicsleeve having an annular packing-support surrounding the pipe, saidsleeve being beveled at its lower end and telescopically connected tothe hub thereat, substantially as described.

3. An adjustable external joint for escapepipes, &c., consisting of anupturned hub to rest upon the roof and having its rear wall higher thanits front wall and convexed vertically, and a packing-supportingmetallic sleeve having an oblique lower end, telescopically connected tosaid hub, the hub being reduced in height at its side and rear walls tocorrespond with the pitch of the roof to which it is applied,substantially as described.

4. An adjustable external joint for escape pipes, 850., comprising ahub-like supporting member having an inclined upper end and adapted torest upon the roof, and a sleeve member beveled at its lower end andtelescopically adjustable upon said hub-like member, to compensate forthe roof-pitch, said sleeve member sustaining a packing surrounding thepipe at the upper end of the sleeve member, substantially as described.

5. An adjustable external joint for escapepipes, &c., comprising acast-iron hub-like member having one or more grooves therein, whereat itmay be reduced in height and a sleeve member adjustable upon thehub-like member, to compensate for the roof-pitch, said sleeve membersustaining apacking and poured joint, about the pipe, substantially asdescribed.

6. An adjustable external joint for escapepipes, &c., comprising a hubhaving a laterally-extended base to rest upon the roof, and a sleevemember telescopically connected to and adjustable upon the hub, to varythe angle between them according to the roof-pitch, said sleeve membersustaining a packing between it and the pipe, and a gasket or packingbetween its lower end and the hub, substantially as described.

7. An adjustable external joint for escape pipes, &c., consisting of ahub-like supporting member adapted to rest upon the roof, and having aninclined upper end a sleevelike member beveled and telescopically con-ITS nected at its lower end to the hub, to COlIlname to thisspecification in the presence of pensate for the roof-pitch, said sleevesnrtwo subscribing witnesses. rounding the pipe above the roof, andmeans to prevent the entrance of moisture between FREDERICK NIES. 5 thepipe and sleeve, substantially-as de- \Vitnesses:
